JOHN 5. Me COMB/E Patented Aug. 7, 1951 UNITED STATES PATENT OFFICE PHONOGRAPH RECORD INDEXING DEVICE John E. McCombie, Waterloo, Iowa Application November 22, 1946, Serial No. 711,661

6 Claims.

ferred embodiments of my invention.

It is, however, to be understood that my invention is not to be limited or restricted to the exact constructions and combination of parts described 7 in the specification and shown in the drawings,

but that such changes and modifications can be made which fall within the scope of the claims appended hereto.

In the drawings:

Figure 1 is a top plan view of an indexing device according to my invention attached to a phonograph record fragmentarily shown in broken lines.

Figure 2 is a fragmentary elevational side view of the indexing device illustrated in Figure l and shown in a bigger scale.

' Figure 3 is a fragmentary top plan view of the indexing device shown in Figure 1 detailing the arrangement of the spring-biased slide.

Figure 4 is a top plan view of an indexing device according to my invention attached to a phonograph record shown in a reduced scale.

Figure 5 is a perspective view of a modified form of the indexing device according to my invention.

Figure 6 is an end view of the indexing device shown in Figure 5. r

Referring now in detail to the drawings, and especially to the Figures 1, 2, 3 and 4, the indexing device forming the subject matter of my invention has a wire arm or frame Ill preferably made from one continuous piece of wire. This frame I comprises a straight shank I I consisting of two wire bars Ila. and I I?) extending parallel to each other and connected together at their front ends by a curved wire portion I2, which is bent downwardly to extend parallel to the shank I I and to form a hook I3.

The Wire bar IIa extends rearwardly beyond the other wire bar IIb and is then bent laterally at right angles, as at I 4, and extends then forwardly for a short distance, as shown at I5. The

wire then extends inwardly parallel to the portion I4 to form therewith the rear arm I6 of a window frame 11, and then forwardly parallel ,to the wire bar I la forming the longitudinal member I8 of said window frame. Then the wire-is bent laterally, as at I9, forwardly, as at 20, and then parallel to wire portion I9, as at 2|. -This wire portion 2| is connected with the shank bar Ilb by welding or the like.

A wire latch slide 22 is formed so that it has a rearwardly extending member 23 on the forward end of which a half-loop 24 is formed. From this half-loop 24 a wire portion 25 extends forwardly and ends in a second half-loop 26. A downwardly bent arcuately closed front portion 2'1 extends forwardly from-this second half-loop 26 and on its end a third half-loop 28 is formed which is connected by a rearwardly extending straight wire portion 29 with a fourth half-loop 30. From the last-mentioned half-loop the wire extends straight rearwardly, as shown at 3|, and is then bent laterally to-form the rear portion 32 of the slide 22. The half-loops 24 and 30, and 26 and 28, are arranged oppositely to each other so that they are adapted to partially encircle the shank bars I Ia. and I Ib and slide thereon toward and away from the hook I3.

Two window panes 33 are secured to the window frame I! by means of hollow rivets 34 arranged between the window frame portions Ila and I8, the member of the window frame rear arm I6 and the wire portions I9 and 2 I. The window panes are preferably made from a diaphanous plastic material, such as Plexiglas or the like.

A U-shaped spring 35 is arranged between the two window panes-33 so that it surrounds the rivet 34 located between the wire portions I9 and 2|. The rear leg 36 of the U-shaped spring 35 engages the wire portion I9 and the end of the front leg 31 of the spring engages the rear end of the wire portion 23 of the slide 22, urging said slide forwardly. The lower end of the front leg 31 is located between the free end of the wire portion 23 of the slide and the rear portion 32 thereof, which portions 23 and 32 cooperate to provide a detent. The expansion of the spring 35 is limited by the wire portion 2I which is engaged by the front leg 31 of the spring. In this manner the forward movement of the slide 22 is limited.

A card (not shown) bearing name and number of a phonograph record 38 may be inserted between the two window panes 33 and then the in- ,dexing device-can be loosened and removably attached to the corresponding record by moving the latch slide 22 rearwardly against the pressure of the spring 35, inserting the hook in the center hole 39 of the record 38 and permitting the latch slide to move forwardly under the pressure of the spring to overlie the edge of the record.

The front latch finger portion of the latch slide 22 is then located above or below the record 38 securing" the indexing device on the record,but permitting rotary movement of thedevice' on the record, because the forward movement of the slide 22 is limited so that the two front halfloops 26 and 28 do not engage-the circumferential edge of the record.

In Figures 5 and 6, a modificationof"theindex device according to my invention-is illustrated. This modification comprises a frame 40 shaped like a thin flat elongated bar or piateand made from any suitable material, such as metal,

paper; plastic,=' 'or J the" like. 'On 'one end of this frame We hoo'k l I is '=formed'- adapted to: engage the c'enter hole 39"of the record 38.

a distance from ithis' ho'oka latch'fl made from metal '-or plastic -'is"rotatablyrmounted on the frame and has a finger-like poi tion 43 "located in the same plane as' the hook 'fl. A stop -isprov'ided on the-frame adapted to prevent the latch 42 from execii-ting a'. fiill S60"r0tary =-movement.

On the end of the firame#Hl'opposite'the hook ll two window panes' 4-5 are-fastened to the frame lfl by means-'of-h'ollow rivets 46. The window panes are preferably "made from transparent "pl'astic-material.

"This modified-dorm "of' my indexing device can be 'removably attached 'to a record by adjusting -"the' latch "4 2 -to extend transversely-of the frame, ln'serting-the hdok 1 4 l into-the "center hole or a record and positioning the-latch-so -that' tl'le latch "finger l3 *extendspverthe record.
